A Story of Braille (E)
Braille is a tactile writing system used by people who are visually impaired. It is traditionally written with embossed paper. Braille is named after its creator, Louis Braille, a Frenchman who lost his sight as a result of a childhood accident. Braille books are cumbersome and heavy. So far replacement for Braille books has not been successful. Available imported assistive technologies are not cost-effective and are not affordable to everyone.
